Product description

Introduction

The PPM-HLV-2 3in1 oil condition monitoring sensor is online oil analysis sensor. It adopts piezoelectric resonant MEMS element, through the internal set. The high-precision signal sampling and processing unit, combined with the built-in algorithm, can Real-time automatic detection of three indicators of liquid density, viscosity and temperature.

Measurement parameters

Note: The factory default is calibrated by No. 68 hydraulic oil. The measurement accuracy must ensure that the test environment is within the range of 20±5°C and the flow rate is 30±5ml/min.
